Title: Process for producing an adapter for the gastight connecting of a plastic pipe to a metal pipe
Inventor: LOEFFLER GERHARD
IPC: F16L47/24
Filed: 1986-08-27
Abstract: The invention relates to a process for producing an adapter for the gastight connecting of a plastic pipe to a metal pipe. The adapter comprises a metallic section, which is positively connected to a plastic section with at least partial thermoplastic deformation of the latter in such a way that the connection can withstand the expected tensile and torsional loads, and also a sealing ring of soft material clamped between the two said sections. In order that the adapter can be produced simply and inexpensively, it is provided that first of all the sealing ring is fitted on the metal section with prestress and then the connection between the two sections is established while maintaining the prestress.
Patent DE-3630085-A1 (DE)
Title: Shock absorber
Inventor: BREITENBACHER JUERGEN
IPC: F16F9/512
Filed: 1986-09-04
Abstract: The proposal is for a shock absorber (damper) which has a device which reduces the static friction which arises in the shock absorber. The shock absorber consists of a casing tube (1) in which a damping piston (5) and a tube (15) connected to the damping piston (5) are mounted with the ability to slide axially. In the tube (15) is a piston rod (20) and the piston rod (20) and the tube (15) can be moved relative to one another counter to the force of compression springs (33, 34). A vibration generator (40) generates a periodically reversed axial force in the damping piston (5) and in the tube (15), with the result that the damping piston (5) and the tube (15) are in a state of continuous motion relative to the casing tube (1), thereby largely avoiding static friction between these parts. The shock absorber operates almost without static-friction-induced force and travel delay and its damping action therefore starts very gently. <IMAGE>

Patent DE-3635053-A1 (DE)
IPC: G02B6/44
Filed: 1986-10-15
Abstract: In the process, the optical waveguides are mechanically pretensioned with respect to the component or in themselves to such an extent that for all the deformations to be expected in the component their stress remains within the tensile range. This results in the avoidance of compressions of the fibres of the optical waveguide which lead to undesired attenuation of the light pulses transmitted through the optical waveguide and corrupt the measurement result in connection with stress monitoring.

Patent DE-3640807-A1 (DE)
Title: Finger ring
Inventor: CAPOL URS
IPC: A44C9/02
Filed: 1986-11-28
Abstract: The known finger rings can turn in their ring plane on the finger since the finger knuckle often has a larger outside diameter than the actual phalanx of the finger, which means that precious stones on such finger rings can become damaged. In order to achieve a fixture of the finger ring on the finger, a ring rail is provided which, by means of a screw and by the counteraction of two springs, leads to the inside diameter of the actual ring rail being reduced.

Title: Auxiliary high-speed planetary gear unit for machine tools
Inventor: WITTENSTEIN MANFRED DIPL ING
IPC: B23Q11/08
Filed: 1987-03-30
Abstract: Auxiliary high-speed planetary gear unit for machine tools, in particular drilling machines. Known gear units of this type are of quite complicated construction and permit no output speeds reaching up to 30000 rev/min at least at low operating noise. Furthermore, the sealing of the interior space and the gear cooling cause considerable difficulties in such gear units. In this respect the novel gear unit is intended to bring about improvements. The gear housing (1) is a hollow cylinder provided at one end with an inner annular collar. A hollow gear (8) for the meshing of the planet gears (7) of the revolving carrier (3) is made in the hollow cylinder. All bearings (12, 13; 15, 16) between the revolving carrier (3) and the gear housing (1) on the one hand and the output shaft (tool-mounting spindle 9) on the other hand are secured via a total of only two clamping elements (14, 17). One of these clamping elements is a ring nut (14) axially closing the gear housing. The seals (18, 19) acting to the outside have filled grease chambers (23) in the housing interior. The gear unit is cooled at housing cooling ribs (25), in particular by an air flow which is produced during operation of the gear unit by a disc (26) fastened to the tool-mounting spindle (9) directly in front of the gear housing (1). <IMAGE>

Title: Method for synchronising a frame for subsequent decoding of additional information contained in digital signals
Inventor: ASSMUS ULF DIPL ING
IPC: H04J3/12
Filed: 1987-05-22
Abstract: Method for synchronising a frame for subsequent decoding of additional information contained in digital signals. Additional information is transmitted along with audio signals which are digitally coded in blocks in each case comprising 64 samples, each sample comprising 14 bits and one parity bit, in that individual parity bits (sync word) or a group of parity bits (scale factor, additional data) are negated or are not negated. The frame is synchronised through detection of the 4 parity bits with the information of the sync word. The search for the sync word is carried out bit-by-bit in that each bit of the data string is first subjected to the decoding algorithm, i.e. parity formation over 7 bits (1, 2, 3) and comparison of the parity bit thus created with the 15th bit of a 15-bit group (4), and that the 4th bit of the sync word is then searched for at 15-bit intervals in this decoded data string (5, 6, 7, 8). The method can be used for the transmission of digital audio signals in a future integrated-services broadband network (ISDN-B). <IMAGE>

Title: Device for operating a friction clutch disengageable counter to a spring force
Inventor: REINECKE ERICH DIPL ING
IPC: F16D25/12
Filed: 1987-06-11
Abstract: Due to the construction of a friction clutch engageable by spring force, the position of the release element (4) of the friction clutch changes relative to the transmission mechanism (5, 6) in engagement with the release element (4) as the friction lining wears. Compensation of the wear of the lining or maintenance of the engagement conditions of the friction clutch can be achieved, for example, by changing the length of the transmission mechanism (5, 6) or by changing the distance between the actuating device (1, 5, 6) and the release element (4). The compensation of the wear of the lining is achieved by means of an automatic change in the length of the transmission mechanism (5, 6) while maintaining a constant pressure-chamber volume (3) of the device during the entire service life. The automatic change in length is achieved by means of an adjusting device (7, 8) which is integrated into the transmission mechanism (5, 6) and permits a relatively short overall length of the actuating device (1, 5, 6). The device is particularly suitable for operation by compressed air. <IMAGE>
Patent DE-3719987-A1 (DE)
Inventor: VOLLGOLD GUENTER
IPC: H02P7/03
Filed: 1987-06-15
Abstract: A gearbox for small gears comprises a switch for reversing the direction of rotation of an engine. The shaft of the engine imparts a rotary motion to a gear drive shaft which, in one direction of rotation, imparts a rotary motion in the same direction to a gear drive shaft through a first gear stage and, in the opposite direction of rotation, imparts a rotary motion in the same direction to the said gear drive shaft through a second gear stage. To avoid abrupt changes of speed an to ensure continuous regulation, the speed of the engine (1) can be changed by a double-layer variable resistance (8) which can be adjusted by a sliding contact (7) coupled to the switch (5) for reversing the direction of rotation. In the first switching position of the switch (5) for reversing the direction of rotation, the sliding contact (7) contacts the first layer (8') of the resistance and in the other switching position it contacts the other layer (8''). The switching operations of the switch (5) for reversing the direction of rotation are carried out in the intermediate position between the two layers (8' 8'').

Filed: 1987-12-04
Abstract: A throttle valve having a valve housing (1) with an inlet duct (2) and an outlet duct (3) is provided with throttling means arranged in a longitudinal duct in the valve housing. The throttling means comprise a first group of radial throttling ducts (20) and an axially spaced downstream second group of radial throttling ducts (14). A first valve seating (18) is located between the first and second groups of throttling ducts and a second valve seating (34) is located downstream of the second group of throttling ducts (14). Valve closing means comprises a first sliding element (30) having a sealing face (32) arranged to mate with the valve seating (18), and a second sliding element (31) having a sealing face (35) arranged to mate with the valve seating (34). The two sliding elements may be capable of limited reciprocal movement relative to one another so that one sealing face leaves its associated valve seating before the other and the radial throttling ducts are so arranged that fluid medium flowing through the valve is forced to follow a meandering path and wear of the valve seatings as a result of erosion is minimised. The throttle valve is particularly advantageous for very great drops in pressure. <IMAGE>
